Lightning has always been a dangerous threat to the equipment of electric power systems consisting of: power plants, substations, transmission lines and distribution lines. Generally, overhead high-voltage transmission lines are exposed to lightning strikes. Therefore, the degree of protection against lightning is determined based on the degree of insulation of the equipment. To prevent damage to equipment due to lightning strikes, arresters are used. In this study, three arrester models were used as comparisons, namely. IEEE arrester model. The system was simulated using Alternative Transients Program (ATP) software. The results showed that the lightning rod was declared successful in protecting the transmission system, where the three lightning rods had a Margin Protection (MP) of arresters that reached 28%. In the simulation, it is known that the IEEE arrester successfully cut off the lightning current in the transmission system so that the transient overvoltage recorded on the transformer does not exceed the Basic Insulation Level ((BIL) trafo.

Idle time or disturbing time is time wasted while the ship is moored is a classic problem that has not been solved in Indonesia. Tanjung Emas Port is the busiest port in Semarang City, Central Java, which is a stopover center for providers of sea transportation facilities and infrastructure in the context of loading and unloading means the transfer of cargo from and onto ships to be stockpiled into or directly transported to the place of the owner of the goods through the port dock using loading and unloading complementary equipment. This study aims to determine the effect of port services, ship engine tools, and loading and unloading productivity, on Idle Time at Tanjung Emas Port Semarang. The population in this study were ship crews from the deck departement division and the sample used in this study was 119 respondents. And do not use the sampling technique because the number of samples is the same as the population, then the data is analyzed using multiple liniar regression with the help of (software) Statistical Package (SPSS) Version 26. The formulation of the regression in this study is as follows: Y= 0,597 + 0,368X1 + 0,356X2 + 0,213X3 + m. From this equation it is know that the most dominant variable influencing Idle Time is the port Service variable with a regression coeffient of 0.368. The R2 test ( R The ) obtained a result of 0.443 or 44.3%, which means that Idle Time is influenced by the variable port Services, Loading and Unloadng Speed, and Ship Machinery Equipment which is equal to 44,3% and other factors that affect Idle Time Tanjung Emas Port Semarang, namely 100%.

Based on the research results, it can be seen that the research model of the multiple linear regression equation is Y= -0.219 + 0.308.X1 + 0.200.X2 + 0,192.X3 + 0.349. X4 + µ. Where the variables Safety (Y), Telecommunication Equipment (X1), Crew Resources (X2), Ship Seaworthiness (X3) and Guidance (X4) were tested using the t test showing that the four independent variables partially have a significan t influence on consumer decisions as the dependent variable. The Adjusted R Square figure of 0.837 shows that 83.7 percent of consumer decision variables can be explained through the four independent variables in the regression equation. Meanwhile, the remaining 16.3 percent is explained by other variables outside the four variables used in this research.
